Hey! Sorry for the bad quality image (my scanner's pretty bad) but I did try to edit the picture to fix the quality a little. Eh.

What the man is wearing is called a hanbok, which is a traditional Korean clothing. I'm not Korean myself but I've watched loads of sageuk (historical Korean dramas) so there are lots of hanbok-wearing characters floating around in my (empty) head.

Kkonminam (what's written in Hangul on the lower left corner) is a Korean term that means 'pretty boy' XD hehehehehehe

Very well drawn. It's also worth nothing in real historical times in Korea not many people wore those colorful and bright Hanboks like they do in dramas. In fact only the rich, royal or those serving under royal had those colored Hanboks. Instead the rest of the populous had very dull and neutral colors such as white, brown, black, grey and maybe dark green if they were lucky.
